Road marker



Jan. 20,- 1931. J. R. o'BRlEN ROAD MARKER Filed Aug. '7' 1925 @277335 7?om? 073mm a nut or collar 17 may be threaded upon the bolt 12 so as toengage the lowerV face of the plate 11 and thereby assist in securingthe anchor bolt to the plate 11.

When the marker element thus constructed is placed, in position therecess in theV pavement is filled in with concrete or anyY suitableplastic material so as to hold the same in position.

Anchor members `18 may be 'p-rovided'iffdesired, and are adapted'to bethreadedupon the bolts 12 so as to project therebelow and form anadditional means for assistingin anchoring the element.

lVith the present invention it Willbe mani# fest that the lateral or*uprightv faces of each of the marker elements` is substantiallystraight, and as the edge of the plete 1.1 is flush'ivith the. lateralface ofthe bedy portien of the marker element, a plurality of thelelements may be placed side by side so as to abut, as shown in Figure 1.This renders it'possible to build up, by the use of a plurality of thesemarker elements, any de sired character such as letters or the like andby securing the adjacent marker elements together the entire built upcharacter may be placed in a pavement and anchored as a unit. i

Any suitable means maybe provided for binding or connecting therespective elements together. Any effective and efficient means embodiesa plurality of plates-,or members 19 provided with suitable aperturestherethrough, and these plates or members 19. are adapted Vto -besleeved' upon theV proximate. bolts or anchor members 12 of the adjacentmarker sections so that the plates 19 will eX- tend across the abuttingedgesof the adjacent lates 11. Y l

After-the marker elements` have been as sembled or adjacent elementsarranged'inV proximity to each other, the respective plates 19 areplaced in position. The nuts or collars 17 are then threaded upon thebolts or` meme. bers 12 and cooperate with the respective heads 13 ofthe bolts for clamping the mem bers 19 against the lower face of theadjacent plates 11, as shoivnmore clearly in Figures 2 and 5. f

In assembling or forming any desired character it is preferableto invertthe marker elements so that the plates-19 and collars or nuts 17 Iny bereadily placed in position.

The additional marker elements 18 are then attached to any desirednumber or all of the bolts 12, after which the assembled charac terA maybe placed in position in the pavement 16by inserting the same into a.recess formed in the pavement; The recess may then be filled Withconcrete or plastic material, and the marker is placed in position sothat theupper face of the body portion 10 thereof will be substantiallyflush With the exposed surface of the pavement.-

vreason-cf sueh'resiliency the life of the element Will be greatlyprolonged.

lThe non-resilient plate which is firmly anchored in the pavement willprevent the element from becoming detached or displaced with respect tothe pavement.

By reason ofthe non-resilient nature and Y of the material of which theplate l11 iS.. c011- structed, it will not be affected by theaction ofheat. or cold, With the result that the element will always be firmlyanchored.

The resilient upper por-tionor bodyl of the. blockvvill yield with thepavement and will not be torn away from the adjacent .faces 0f the Wallof the openingin the pavement into.

which theelement is inserted. Y

It.. will also be manifest that Withthi's improved element any form. ofletter or character may be built up .by the fuse. of a plurality of theelements and the elements may all be secured together so. as toconstitute a Single. 1111113. 1

Obviously'many changes may be made, in the details of' construction andin the combi nation and arrangement-of the several parts, within thescope of the claims, Without. de,` parting from the spirit of thisinvention.,

What is claimed asnew is z:-

1.l A road marker embodyinga plurality of elements each embodying aresilient .block like body portiom the Vupper surface. beingsubstantially fla-t, a noni-.resilient pla/te4 upon which the blockrests, the lower surface ofthe block andsaid plate beingsecuredtogether, the edge ofrthe plate being-substantially flush With the,lateral Wall of the block,v an anchor member connected with the plateand. de-- pending thcrebelow, the proximate faces of adjacentelementsabutting, and a connecting 1 member extending across. the jointbetween adjacent elements and secured to one of the anchor members ofeach ofthe elements.

2. A road marker embodying aplurality of elements each embodying` aresilient block like body portion, the upper surface, beingsubstantially flat, a non-resilient plate upon' which the block rests,the lower surface of the block and said plate being secured together7the edge of the plate being substantially flush with the lateral Wall ofthe' block, an anchor member connected With-thek plate and dependingtherebelow, the'proximate faces of adjacent elements abutting, a.connecting member extending across the joint between adjacent elements,and means securing the ISO connecting member against the exposed face ofthe said plate.

8. A road marker embodying a plurality of elements each embodying aresilient body portion, a non-resilient plate upon which the said bodyportion rests, the lower face of the said body portion and the platebeing secured together, the edge of the plate being substantially flushwith the lateral edge of the said body portion, an anchor bolt connectedwith and depending below the plate, said bolt being threaded, theproximate faces of adjacent elements abutting, a tie member extendingacross the joint between adjacent sections and engaging said bolts, andnuts on the respective bolts for securing the said tie member inposition and for clamping it against the lower face of the said platefor securing the said elements together.

4. A road marker embodying a plurality of elements each embodying aresilient body portion, a non-resilient plate upon which the said bodyportion rests, the lower face of the said body portion and the platebeing secured together, the edge of the plate being substantially flushwith the lateral edge of the said body portion, an anchor bolt connectedwith and depending below7 the plate, said bolt being threaded, theproximate faces of adjacent elements abutting, a tie member extendingacross the oint between adjacent sections and engaging said bolts, nutson the respective bolts for securing thesaid tie member in po-l sitionand for clamping it against the lower face of the said plate forsecuring the said elements together, and an additional anchor elementconnected with the said bolt.

5. A road marker embodying a plurality of block like body portionsadapted to be embedded in a pavement with their upper facessubstantially flush with the surface of the pavement, an anchor memberconnected with and depending below each of the blocks, and a fasteningmember extending across the .f bottoms of adjacent blocks and engagingadjacent anchor members for securing the marker elements together.

6. A road marker embodying a plurality of block like body portionsadapted to be embedded in a pavement with their upper facessubstantially flush with the surface of the pavement, an anchor memberconnected with and depending below each .of the blocks, a fasteningmember extending across the bottoms of adjacent blocks, said fasteningmember having apertures therethrough through which the respective anchormembers pass, and means engaging the said anchors for clamping the saidfastening member against the lower face of said body portion forsecuring the marker elements together.

7 A road marker embodying a plurality of elements each embodying aresilient block like body portion, a non-resilient plate upon which theblock rests, the lower surface of the block and said plate being securedtogether, the edge of the plate being substantially flush with thelateral wall of the block, an anchor member connected with the plate anddepending therebelow, and a connecting member below the elements andextending from one element to the next adjacent element and secured toone of the anchor members of each of the elements.

8. A road marker embodying a plurality of elements each embodying aresilient body portion, a non-resilient plate upon which the blockrests, the lower surface of the block and thesaid plate being securedtogether, the edge of the plate being substantially flush with thelateral wall of the block, an anchor member connected with the plate anddepending therebelow, a connecting member below the elements andextending from one element to the next adjacent element, and
